Energy Cost per Shower
Produced by Jacob
You will be figuring out how muchenergy each shower uses and then calculate what the cost is for each shower to run. The purpose of this activity is to show how much it really costs for each time you take a shower; you may or may not be surprised by the results.
Materials List:
Extra paper (for solving equations)
Pencil (for recording data)
Computer (to search for data)
Procedure
1. Get all the supplies necessary to obtain the information that you will require. This includes this paper, a pencil, a computer; and an extra piece of paper to solve equations for further steps.
2. Go to the following website
http://10.14.4.9/cgi-bin/EMCcgi
3. Locate the Datum Keyword in the top middle of the webpage and search "Perry"
5. Obtain the two times for which you are going to record shower data for; have these be for one shower period (you'll be able to tell).
6. Subtract the larger gallon amount with the smaller one to obtain the gallons and then convert that into grams
7. For the same time selected subtract the two temperatures and find the temperature in Celsius to obtain the Change in temperature.
8. Find Energy Used by using the equation in Useful Information.
9. Find Cost.

Useful Information
Equation for finding heat:
Q(energy used) = grams(mass) x Water(1.00) x Change in temperature(IN CELSIUS)
Equation for Converting F to C:
(F - 32) .5556 = C
Information for gallons and grams:
1 Gallon = 9109.71 Grams
Finding kWh:
kW x 5Hours = kWh
Cost Per kWh = .5$
Observations:
Record your Observations and correctly solved equations here.
Conclusion/Error Analysis
Record your conclusion and if you think you produced human error; and how you could fix those theoretical mistakes.
